Review

The Book

This step-by-step text introduces the complete beginner to Z80 programming in the well proven style that has been described by the critics as “worth its weight in gold“. No prior knowledge is assumed and the aim throughout the book is to ensure that the beginner realty succeeds. By the end of the book every Z80 dass of instruction has been explained in detail. Numerous examples illustrate the points while exercises (along with solutions) test the understanding. Later chapters show how additional commands may be added to BASIC including, for example, a circle drawing routine.

The Associated Software

The software available to accompany this book includes a complete Z80 assember with:

  • Symbolic Labels
  • Hard-copy
  • Assembler Directives
  • Insert/Delete
  • Save/Load

The assembler allows programs to be written easily in assembly language and these it translates into machine code. To help understand the mathematical notations used, a binary hexa decimal tutor is included. Also included is a program demonstrating the use of the additional graphics commands described in the book.
